Your statistics professor was interested in the extent to which class attendance predicted test performance (% test score) in Introductory Psychology. An analysis of the data revealed the following information:N = 127; rxy = .518Mx = 17.43; SDx = 4.21; SSx = 2248My = 71.46; SDy = 12.82; SSy = 20888The formula for the regression line was calculated as = 43.941 + 1.579X. Using this information calculate the adjusted r2.
